Abstract
Humic substances have an essential function in soil fertility and are viewed as being of prime importance for soil aggregation stability. Humic substances as part of humus-soil organic matter are chemicals generated from the biomolecules physically, chemical and microbiologically (humifying). It is essential since it is the most pervasive biological material source, which nature knows. Roughly 80 percent of total carbon is produced with terrestrial humic compounds and 60 percent of the water dissolved carbon. During the last three decades there have been challenges in two major approaches, the concept of soil humic substances. Much of the organic aromatic soil originates from the carbon that is frequently known as black carbon (black carbon). However, the detection of benzene polycarboxylic acid markers and the UV technique in soil with two commonly used methods is not trustworthy. Polymerisation of phenolic compounds produced from the breakdown and synthesis of lignin microorganisms may result in a wide number of humic chemicals and components including organic molecules and inorganic molecules. The addition of e.g., triazines or tensile compounds that cause to bound residues in the humic matrix demonstrates that humic substances are crucial for clarifying critical soil processes. Plant nutrients, comprising p, fe and cu, are available in soil this is equally essential to understand and can directly influence the growth of higher plants in the soil.
Highlights
Soil organic matter (SOM) is one of the contributing factors for stabilizing soil aggregates, supplying nutrients and maintaining soil microbiology [1]
The majority of them are aromatic in nature, the patterns are variable in aromaticity and intra-molecular weight [36], [53]
Nitrogen can be a structural component of humic substances as a persistent organic material and avoid leaking through the soil depending on the kind of fertilizer used. [60, 61] Humic compounds contain between 1% and 5% nitrogen in their natural condition
Summary
Soil organic matter (SOM) is one of the contributing factors for stabilizing soil aggregates, supplying nutrients and maintaining soil microbiology [1]. The dynamics of SOM are motivated by the addition of organic compounds that are transformed as time passes, a combination of chemical, and biological factors have a role [2], [3] Such transformations When organic matter decomposes, the size of the molecules, chemical composition, structure and functional groups change, along with the polyelectrolytic properties of the supplementary material change [4],[5],[6] In chemical words, three fractions of humic substances (HS) are composed of organic matter: humic acid, fulvic acid and humin [7]. This can be done using Natural aggregates and inorganic ones This technology changes the soil's physical properties, such as porosity, Structural stability, infiltration and other factors that lead to higher water absorption in the soil Reducing surface runoff and preventing soil particle erosion The importance of considering the method characteristics because the methodology affects the results of stability and the opportunity for an estimate of soil erodibility using aggregate stability data is analyzed
